Hydraulic power units (HPUs) pressurize oil to power hydraulic cylinders and equipment. The oil pressure can be adjusted according to user requirements.

Application: core pull cylinder of injection molding machine, hot runner cylinder and other hydraulic transmission devices in molding machinery.

Features

Compact design: a 4-caster mounted base improves the loading capacity and movability.
Imported oil pumps and solenoid directional valves feature a high pressure, large flow, great stability, and long service life.
Water-cooling or air-cooling methods are optional according to the customer's requirements.
A hand-directional control valve is utilized. When the oil inlet tube and the oil return pipe are incorrectly connected, there is no need to completely dismantle the oil tubes: simply adjust the hand directional control valve.
